Ocala, Fla., assignors to Perry Printing Process Company, Ocala, Fla., a corporation of Florida Filed Jan. 10, 1961, Ser. No. 81,738 6 Claims. (Cl. 8824) This invention relates generally to composing machines and particularly to an improved machine for projecting upon sensitized paper adapted for being developed for use in making engravings a composition which is a faithful reproduction of an artists layout.

When a printed advertisement is produced, for example, for a page of a newspaper, the artist makes a layout of his conception, and the photosetter makes a film negative from the artists layout. The photosetter must have regard for the style and size of each character called for by the artist, in consequence of which the photosetter must use a different font of type for each size of print called for. Obviously, this is inconvenient and expensive. Accordingly, an important object of the invention is to provide a machine that is capable of reproducing an artists conception calling for a number of different sizes of print on sensitized paper from a film negative made by using only one size of type at the photosetting machine.

Other objects of the invention will become apparent when the following specification is read with reference to the accompanying drawings, in which:

The frame is provided across the front and rear respectively with members 444 and 446 and along opposite ends thereof respectively with members 448 and 450. Extending fore and aft of the frame, between the member 448 and 450 is a member 452. Extending between members 448 and 452 are a pair of laterally spaced members 454 and 456, and disposed between the members 452 and 450 are three laterally spaced members 458, 460 and 462.

Fitted into the space defined by the. frame members 444, 446, 448 and 452 and extending over the frame members 454 and 456 is a plate member 464. Overlying the marginal portions of the plate 464 is a thin spacer strip 466 secured in position by screws 468. Overlying the strip 466 is a gasket 470. The plate 464 is provided with four grooves 472, 474, 476 and 478 formed in the top thereof. It is also provided internally with passages 480 communicating with the grooves aforesaid by means of a multiplicity of openings 482. I

The frame is provided with a cover, generally designated 484, fitted with a pair of brackets 486 which mount rollers 488 adapted to work in grooves 490 formed in the frame members 444 and 446, the grooves being provided with vertical extensions 492. The cover is also fitted with a pair of brackets 494 which mount rollers 496 adapted to work in grooves 498 formed in the frame members 444 and 446, the grooves being provided with vertical extensions 500. Depending from the frame are a pair of rods 502, each of which has fitted thereover a compression spring 504, the lower end of which is seated upon a lug 505 aflixed to the top 12.

The cover 484 is secured as by a pin 506 to a chain 508, which chain is trained over a sprocket 510 and a sprocket 512. The sprocket 510 is mounted upon a shaft 514 which also carries a sprocket 516. Over the sprocket 516 is trained a chain 518, which is also trained about a sprocket 520. The sprocket 520 is mounted upon the output shaft 522 of a speed reducer 526, the latter being associated with a motor 528 carried by a bracket 530.

Referring particularly to FIGURE 12, the artists layout 532 may, for example, include an underscored heading 534. A border 538 extends about the advertisement, generally designated 540, which includes upper case print, as, for example, the word Fryers, designated 542; upper case print smaller in size, as, for example, the word Whole, designated 544; lower case print, as, for example, the words salad dressing, designated 546; and lower case print smaller in size, as, for example, the words Limit 1 please, designated 548.

' Referring particularly to FIGURE 11, the photosetters negative, designated 500, is provided with a series of holes 552 on each side thereof. The printing to be projected appears on the negative, and it will be noted that in preparing the negative the size of the printing on the artists layout is ignored, i.e., only one size of type is set at the photosetting machine. While all printing appearing on the negative is the same size, for example, eight point, the style of the printing must correspond character for character with thatof the artists layout. Thus it will be apparent that one and the same photosetting machine may be used for a wide range of type sizes called for by the artist, but the operator must change fonts of type each time the artist calls for a different style of type. Each line of the negative contains only what is to be projected at one and the same time. If more than one line are to be projected simultaneously, each must be suitably centered relative to the others, as illustrated within the rectangle 554 encompassing the printing in the second and third lines.

In the operation of the machine, first the artist makes a layout of the advertisement, for example, an advertisement for a newspaper page, as illustrated in FIGURE 12.

Then the photosetter makes a negative from the artists layout, as illustrated in FIGURE 11. The artists layout 532 is taped to the top of the cover 484, as shown in FIGURE 8. The photosetters negative is threaded foot first between plate 220 and shutters 232 and 236, between rollers 276 and280, and through opening 246, whereupon motor 254 is operated to actuate roller 276 through the chain 258, shaft 262, chain 268 and shaft 272. Thus the negative is loaded into magazine 310. When the head of the negative is in the projection area, i.e., the area between shutters 232 and 236, operation of motor 254 is terminated.

Assuming that the Word Fryers is to be projected, the shutters are adjusted for one line projection by manipulating hand wheel 306. The hand wheel and sprocket 300 turn together, actuating chain 298, whereupon sprocket 296, shaft 292 and sprockets 290 are actuated and chains 286 turn sprockets 288. Thus the shutters may be adjusted as required to make the opening between the shutters of the required size.

The negative is now fed from the magazine 310 in print direction, i.e., toward the magazine 308, by reversing the motor 254. When the word Fryers is in registry with the opening between the shutters, operation of the motor is terminated. Now a work light (not shown) is turned on, and the projector is focused in the manner to be described so that the projected word Fryers registers with the word Fryers on the artists layout.

In focusing the projector, the knob 192 is manually moved fore and aft until the projected line registers with the corresponding line on the artists layout. When the knob is moved fore and aft, the plate 188 slides along the arm 50, actuating the chain 178, shaft 172 and chain 142.

Referring particularly to FIGURE 2, one horizontally extending loop of the chain 142 is lengthened and simultaneously the other horizontally extending loop is shortened, whereupon the carriage unit 186, which mounts the projector assembly 286, is moved fore or aft, the bars 108 sliding in bearing units 188 and 182. At the same time, the shaft 358 moves axially relative to the roller unit 362, the rollers 364 respectively working over the surfaces of the shaft 358.

The projected line being in registry (lengthwise of the artists layout) with the corresponding line on the artists layout, the knob 192 is now moved manually crosswise of the machine till the projected Word and the corresponding word on the artists layout register crosswise of the artists layout. When the knob is moved as aforesaid, the carriage unit 32 slides along the several bars 24, 26 and 54 and carries with it the carriage units 96 and 106. The carriage unit 96 slides along the bars 94. The chain 72 and the cable 78 respectively trained over the sprockets 74 and pulleys 88 and tied together at 82 make movement of the carriage 32 smooth.

The projector assembly 206 is now moved vertically in order to make the size of the projected letters correspond with the size of the letters on the artists layout. This is effected by actuation of electric motor 194 as required to actuate chain 198. When the chain 198 is actuated, the carriage unit 96 moves vertically, sliding on the bars 64 and 66, and carrying with it the carriages 86 and 106. The weight of the vertically movable assembly is balanced by counterweights 126 and 138.

As the carriage unit 96 moves vertically, the roller 372 works on the cam 390, and the carriage 378 moves up and down on the plate 384. Thus the arm 356 afiixed to the shaft 358 rocks about the axis of the shaft. As a result the link 352 actuates the bell crank, rocking it about the pin 348. The bars 312, through the cables 320 and 336, are shifted axially, raising or lowering the bellows 222 relative to the header member 110. Thus, by moving the projector assembly 206 vertically as a whole and by varying the effective length of the bellows and lens, the size of the projected letters is varied as desired. For example, typically, the projected characters may range from one to eight times the size of the characters on the negative. The range may be increased by a suitable change of readily available lenses. The projected image and the corresponding poition of the artists layout now registers letter for letter in size, position and type of print. The spring motor 398, of course, supports the bellows 222 and lens 226, the cable 402 being extended and reeled in as the bars 312 are shifted axially. The work light is no longer needed, and therefore is turned oif, either manually or automatically, in which latter event it is controlled by movement of the vacuum board cover.

Now the motor 528 is operated to actuate chain 588 through chain 518 and shaft 514. Thus the cover 484 is shifted from its closed position, shown in FIGURE 7, to its open position, shown in FIGURE 8. When the cover starts to move toward its open position, pneumatic motor 420 automatically operates to actuate the several cams 436 through chain 418 and shafts 410. Thus the frame 438 rises, positioning the plate 464 with its upper surface at 8 an elevation corresponding to that of the cover when the latter is in closed position.

A sheet of sensitized paper (not shown) is now fitted to the plate 464, and vacuum is applied through passages 488 and openings 482 to hold the paper in position. The exposure lamp is now turned on, whereupon the image to be projected is cast upon the sensitized paper, and after a predetermined time, the exposure lamp automatically goes off again. It will be understood that the procedure outlined hereinbefore is repeated over and over again until each line of the advertisement has been projected to the sensitized paper. It should be noted, however, that instead of projecting one line at a time a plurality of lines may be projected simultaneously, for example, the two lines enclosed by the rectangle 554, FIGURE 11. After each projecting operation, the cover automatically returns to closed position and the pneumatic motor 428 automatically operates to relower the frame 438 to its initial position. Finally vacuum is removed so that the sensitized sheet of paper may be removed from the plate 464 and developed for use in making engravings.

Referring particularly to FIGURE 15, the control circuit for vertically positioning the projector comprises a set of stop switches S12, S14, S18, S24, S38, S36, S42, S48, S60, S72, S84 and S96, of which only a few are shown arranged in vertical array, on the left side of the machine, as viewed in FIGURE 4. Associated with these stop switches is a selector switch S1, which is shown in FIG- URE 10 on a control panel. The circuit also includes a set of relays respectively designated R1, R1A, RIB, R2, R2A, R213, and R1-2. The circuit further includes a set of push button switches P1, P2, P3 and P4, which are shown on the control panel, FIGURE 10. These switches are single pole switches, P3 and P4 being momentary contact switches. Associated with R113 and R2B are a pair of SPDT limit switches respectively designated LS5 and LS6, which are vertically spaced, on the right side of the machine, as viewed in FIGURE 4. The motor 194 controlled by the circuit is a four lead reversible synchronous speed motor.

The coils of R1 and R1A are parallel with one another and, through a lead 15-16, in series with PB2 across a D.C. supply lead 15-1 and a D.C. return lead 14-8. The coil of R13 is connected in series with PB4 across leads 151 and 15-8. The coils of R2 and RZA are parallel with one another, and through a lead, 15-17, in series with PB1 across leads 15-1 and 158. The coil of R2B is connected in series with PB3 across leads 15-1 and 15-8. The coil of R12 is adapted to be connected in series with any one of the stop switches and its corresponding selector switch contacts, C12, C14, C18, C24, C38, C36, C42, C48, C60, C72, C84 or C96, across the leads 15-1 and 15-8. The leads connecting the stop switches with the selector switch are designated 15-2. The selector switch is provided with a contact ring 15-3, which has a radial extension 154. The pointer of the selector switch, designated 15-7, may be turned to bring the extension 15-4 selectively into engagement With the contact points of the selector switch. The contact ring 15-3 is connected to lead 158 through a lead 15-6 and a stationary element 155, which slidably engages the ring.

The normally open contact of LS5 is connected by a lead 15-9 to the low potential end of the R2B coil, while the normally closed contact of LS5, is connected by a lead 15-10 to the switch section of RIB. The normally open contact of LS6 is connected by a lead 15-11 to the low potential end of the RIB coil, while the normally closed contact of LS6 is connected by a lead 15-12 to the switch section of R2B. The switch arms of LS5 and LS6 are connected to the lead 158. The motor 194 is connected by four leads, designated 15-13, through the R1 and R2 switch sections, to a suitable source of AC.

Assuming that the projector is in an intermediate position, and that it is desired to raise the projector in order to enlarge the projected characters, for example to eightyfour point, the pointer arm 15-7 is turned to a position such that the extension 15-4 of the contact ring 15-3 engages with contact C84. Preferably, PB4 is depressed, whereupon it makes momentary contact. The RIB coil is energized, and through the RIB switch section the R1 and RIA coils are energized. When RIB operates, a circuit (not shown) is set up to hold R1 and RIA after PB4 reopens. When RI operates, the motor leads 15-13 are suitably connected to the source of A.C. through the RI switch section, the motor 194 operates and the projector rises. When the projector reachesthe desired position, the stop switch S84 is mechanically closed by trip means, indicated at 15-14, FIGURE 4. Thus the R1-2 coil is energized and the Rl-Z switch section operates to open the holding circuit set up by RIB, whereupon R1 and RIA are deenergized and current is cut off from the motor. RIA, deenergized simultaneously with R1, acts to deliver to the motor D.C. for braking it, in consequence of which the projector may be stopped to within five one-thousandths of an inch of the desired position.

If, now, it is desired to lower the projector in order to decrease the size of the projected characters, for example to sixty point, the arm 15-7 is turned to bring the extension 1.5-4 into engagement with contact C60. Preferably, P83 is depressed, whereupon R2, R2A and R213 operate to lower the projector, in the same way as R1, R1A and R113 operate to raise the projector. When the projector reaches the desired position, the trip 15-14 closes stop switch 560, whereupon the RI-2 coil is energized, RI-Z opens a holding circuit set up by R213, R2 cuts current off from the motor and R2A supplies DC. for braking the motor.

It, When it is desired to raise the projector, PBS is depressed instead of P134, the projector descends first, then automatically reverses and rises to the desired position. At the limit of the downward excursion, LS6 is mechanically operated by trip means,.indicated at 15-15, whereupon the circuit held by R213 is opened and RIB is energized, reversing the motor. If, when it is desired to lower the projector, PB4 is depressed instead of PBS, the projector rises first, then automatically reverses and descends to the desired position. At the limit of the upward excursion, LS5 is operated by trip 1515, whereupon the circuit held by RIB is opened and R2B is energized, reversing the motor.

The projector may be brought to any desired position within the range of its movement by depressing P132 to raise the projector or depressing FBI to lower the projector, the motor operating to raise the projector as long as P132 is depressed and operating to lower the projector as long as P51 is depressed. Thus odd sizes of projected characters may be obtained so that the copy may fit the space called for by the artist.

Referring particularly to FIGURE 16, the control circuit for actuating the cover 484 comprises a set of relays respectively designated R3, RBA, R4, R4A, R17, R18 and R19. The circuit also includes a SPDT momentary contact toggle switch T53 with center off position, which is shown on the control panel, FIGURE 10, and a single pole push button momentary contact switch PB6, which is shown on the control panel, FIGURE 10. The circuit further includes a pair of single pole limit switches respectively designated LS9 and LS10, which are shown at opposite ends of the frame 438, FIGURE 8. The motor 528 controlled by the circuit is a four lead reversible synchronous speed motor.

When T53 is closed in the open direction, the R4 and R4A coils, parallel with one another, are connected in series with TS3 across the D.C. supply lead 15-1 and the D.C. return lead 15-8. When T53 is closed in the closed direction, the R3 and R3A coils, parallel to one another, are connected in series with T53 across the leads 15-1 and 15-8. The low potential end of the R17 coil is conlead I76, as shown.

10 nected through LS9, by a lead 16-3, to normally open contacts in the R17 and R19 switch sections. The R18 coil, LS10 and PB6 are connected in series across the leads 15-1 and 15-8 by a lead 16-4. Connected to the lead 16-4, between PB6 and L810, is a lead 16-5, which extends to normally open contacts of the R18 switch section. Armatures of the R17, R18 and R19 switch sections are connected to lead 15-8 by a lead 16-6. The low potential end of the R19 coil is connected by a lead 16-7 to normally closed contacts of a relay R15 of the automatic timer circuit for the exposure lamp, to be described hereinafter. The motor 528 is suitably connect- .ed by leads 16-8, through the R3, R3A, R4 and R4A switch sections to a source of AC.

Assuming that the cover 484 is closed, and that it is desired to open the cover, PB6 is depressed, whereupon the R18 coil is momentarily energized and a holding circuit (not shown) is set up for a purpose to appear. Now TS3 is closed in the open direction, whereupon the R4 and R4A coils are energized. The holding circuit set up by R18 holds the R4 and R4A coils energized when the contacts of TS3 reopen. When R4 and R4A operate, the motor leads 16-8 are connected to the source of AC. through the R4 and R4A switch sections, the motor 528 operates and the cover 484 opens. When the cover reaches the end of its excursion, LS10 is opened, whereupon the R18 coil is deenergized, the holding circuit opens, and the R4 and R4A coils are deenergized. Thus current is cut oii from the motor 528. Preferably, D.C. is delivered to the motor 528 for dynamically braking the same.

Referring particularly to FIGURE 17, the control circuit for the exposure light comprises a pair of relays R15 and R16. R15 is provided with a SPDT switch section, While R16 is provided with a DPDT switch section. The circuit is also provided with a transformer T1, a pair of tubes V1 and V2, a pair of capacitors CPI and CP2, a variable resistor RTI, a pair of fixed resistors RT2 and RT3 and a lamp L1. Connected in the circuit are a SP switch S8, which is shown in FIGURES 7 and 8, and a SP push button switch PBS, which is shown on the control panel, FIGURE 10.

PBS, S8 and the R16 coil are connected in series across the leads 15-1 and lead 15-8. A normally open contact of the R16 switch section is connected by a lead 17-3,

through RTI, to the cathode of V1, while normally closed contacts of the R16 switch section are connected by leads 17-4 and 17-5, through the R15 coil, to the plate of V1 and the cathode of thyratron V2. The closed contacts of the R16 switch section, RT2 and CPI are connected in series with one another and in parallel with CP2 across the leads 17-4 and 17-5. The grids of VI are tied to the cathode of V1 and to one of the grids of V2 by a The other grid of V2 is tied to the cathode of V2 by a lead 17-7, as shown. RT3, the R15 coil, and V2 are connected in series across the secondary of T1 by leads 17-8, I7-4, 17-5, and I7-9. The R15 switch section and L1 are connected in series across the primary of TI.

During the positive half of each cycle, V2 conducts, the pulsing D.C. supplied to the R15 coil being suflicient to hold the normally closed contacts of the R15 switch section closed. The capacitors CPI and CP2, of course,

are charged. Assuming that the cover 484 is open, at which time S8 is closed, the operator depresses PBS, whereupon the R16 coil is energized and the normally open contacts close. CPI now begins to discharge through V1. The high bias thus placed on the grid of V2 cuts 011 V2, whereupon the R15 coil is deenergized and the normally open contacts close. The exposure light goes on and stays on for a period of time determined by the time constant of the circuit, which is varied as desired by adjusting RTI. When the bias on the grid of V2 returns to normal, V2 begins to conduct again, reenergizing the R15 coil, whereupon the normally closed contacts reclose, and the lamp L1 goes off.

Now referring to FIGURES 16 and 17, DC. is supplied through normally closed contacts of the R15 switch section to the R19 coil, which has a capacitor CP3 across it. When the R15 coil is deenergized and L1 goes on, the normally closed contacts of the R15 switch section open and the R19 coil is deenergized. However, CPS is operative to delay the opening of normally closed contacts of the R19 switch section until after expiration of the desired exposure period, whereupon the normally closed contacts of the R19 switch section open and normally open contacts of the R19 switch section close. Thus the R17 coil is energized and a holding circuit (not shown) is set up, which circuit energizes the R3 and R3A coils. When R3 and RSA operate, the motor leads 16-8 are connected to the source of A.C. through the R3 and R3A switch sections, the motor 52% operates and the cover 434- recloses. When the cover reaches the end of its excursion, LS9 is opened, whereupon the R17 coil is deenergized, the holding circuit opens and the R3 and RSA coils are deenergized. Thus current is cut off from the motor 523. Preferably, DC. is delivered to the motor 528 for dynamically braking the same. In addition, the work light may be turned on automatically for the next operation.

Referring to FiGURE 18, the film feed control circuit comprises a pair of relays R9 and R10, which have DPDT switch sections. The circuit also includes a half wave rectifier RF1 and a capacitor CR4. The circuit further includes a single pole push button switch PB7 and a SPDT toggle switch TSS with center off position, which are shown on the control panel, FIGURE 10. The motor 254 controlled by the circuit is a three lead reversible synchronous speed motor.

The R9 and R coils are parallel to each other and in series with PB7 across the DC. supply lead -1 and the DC. return lead 15-8. Open contacts of the R9 switch section are connected by leads 18-3 and 18-4 to the source of A.C., while open contacts of the R10 switch section are connected by leads 18-5 and 18-6 to the source of A.C. The armatures of R9 are connected by leads 18-7 and 18-8 respectively to the arm of T S5 and the motor 254. The open contacts of T55 are connected by leads 13-0 and 18-10 to the motor 254. One armature of R10 is connected by a lead 18-11 to one side of RF1, while the other armature is connected by a lead 18-12, through capacitor C1 4, to the other side of RF1, which side is connected by a lead 18-13 to one set of closed contacts of R10. The latter are connected by a lead 18-14 to one set of closed contacts of R9. The other set of closed contacts of R9 are connected by a lead 18-15 to the other set of closed contacts of R10.

When it is desired to load the projector, the tail end of the film is manually started through the projector, as described hereinbefore. Then T55 is closed in the load direction, and PB7 is depressed. The R9 and R10 coils are energized when PB7 is depressed, and the normally closed contacts of both switch sections open and the normally open contacts close. Thus A.C. is supplied to motor 254, which runs so long as PB7 is depressed. At the same time, CP4 is charged through RFl. When the head of the film is in the projection area, PB7 is released, whereupon the armatures of R9 and R10 return to their initial positions, and current is cut off from the motor. At the same time CPd discharges through leads 18-13 and 18-14, supplying motor 254 with DC. for braking the motor. Now T85 is closed in the print direction and PB7 is depressed, whereupon motor 254 reverses and feeds the film head first in the opposite or printing direction.

Referring to FIGURE 19, the arrangement for controlling vertical movement of the frame 438 and the application of vacuum comprises a pair of relays R12 and R13. R12 has a SPDT switch section, and R13 has a DPDT switch section. The arrangement also includes a SP limit switch LS7, which is shown in FIGURES 7 and 8, and a SP toggle switch T32, which is shown on the control panel, FIGURE 10. The arrangement further includes the solenoid 19-1 of a valve which controls the supply of air to the pneumatic motor 420. The motor M1 controlled by the circuit runs the vacuum pump (not shown).

The R12 coil is in series with LS7 across the DC. supply lead 15-1 and the DC. return lead 15-8, while the R13 coil is in series with T52 across the leads 15-1 and 15-8 An open contact of the R12 switch section is connected by a lead 119-4, through the solenoid 19-1, to one side of the source of A.C. One of the armatures of the R13 switch section is connected by a lead 19-5 to the lead 119-4. The other armature of the R13 switch section and the armature of the R12 switch section are connected by leads 19-6 and 19-7 to the other side of the A.C. source. The open contacts of the R13 switch section are connected by leads 119-8 and 19-9 to the motor M1.

Normally, the R12 coil is energized, and the R13 coil is deenergized. When the cover 484 begins to open, it opens LS7, whereupon the R12 coil is deenergized and the normally closed contacts open and the normally open contacts close. Thus the solenoid 19-1 is energized and the valve which it controls (not shown) supplies air under pressure to the pneumatic motor 433 for retracting the piston rod 422, whereupon the frame 430 is raised. When the cover returns, it recloses LS7, whereupon the R12 coil is reenergized, the armature of the R12 switch section returns to its initial position, and the solenoid 19-1 is deenergized. Upon deenergization of solenoid 19-1, the valve aforesaid supplies air to the pneumatic motor for again extending the piston rod 422, whereupon the frame 438 is relowered.

When it is desired to apply vacuum, T82 is closed, whereupon the R13 coil is energized. The normally closed contacts of the R13 switch section open, and the normally open contacts of the R13 switch section close. Thus M1 is supplied with operating current. When T S2 is reopened, the R13 coil is deenergized, the armatures of the R13 switch section return to their initial positions and the operating current is cut off.

Mounted upon the control panel is a toggle master switch T51 which controls the supply of A.C. and DC. to the machine. In addition, the panel mounts a toggle switch T S4, which is connected in a control circuit for the work light (not shown).
